TRB's Airport Cooperative Research Program (ACRP) Report 19A: Resource Guide to Airport Performance Indicators explores airport performance indicators (APIs) for use in benchmarking and performance measurement. These APIs are sorted by functional type and their criticality to the airport strategic plan.
More than 800 performance indicators are presented in three main categories: Core, Key, and Other APIs. "Core" or fundamental indicators are important for overall operation of the airport and of interest to the Chief Executive Officer or governing board. "Key" or departmental indicators are important for the operations of key airport functions and departments. The remaining "Other" indicators are considered useful as secondary departmental unit performance indicators but not critical to the airport's overall function.
The printed versions of ACRP Report 19A include a bound in CD (CRP-CD-94) of the Interactive Resource Guide that is identical to the pdf that is posted online.
